__________ High grade zinc and/or lead concentrates were produced with positive recoveries for each of the four sulphide dominant composites – with zinc recoveries of up to 96.0%, lead recoveries of up to 97.9% and silver recoveries of up to 85.0% Positive gold recoveries from cyanidation were achieved for the upper oxidized mineralized zones, realizing 86.8% for Upper Hilltop and 85.1% for Golden Hill Notably, the composites contain low silica and low deleterious metals, enhancing the expected potential of ...
